Application April 2, 1954, Serial No. 420,550

2 Claims. (Cl. 222-545) This invention relates to improvements in liquid dispensing apparatus. t

An object of the invention is to provide an improved liquid dispensing apparatus adapted to dispense glue or similar liquid quickly, in easily controlled amounts, and with la minimum of required manual operation.

Another object of the invention is to provide an improved liquid dispensing apparatus which is` mounted in dispensing position and which is actuated by linger pressure and automatically closes upon removal of the finger pressure.

Other objects and advantages of the invention will appear in the course of the following description considered in conjunction with the attached drawings, in which:

Figure 9 is a detail plan view of the dimpled spring steel washer of the outlet.

Referring now to the drawings in more detail, the illustrated device comprises an elongated flat base 1, fabricated of metal or other heavy solid material and adapted to support the apparatus rmly upon a desk or work bench. Numeral 2 designates a container containing liquid L to -be dispensed. The container is of elongated closed tubular form and terminates at one end in a reduced, downwardly curved discharge neck 3 having an open lower end. The container 2 is spaced above and carried lby the `base 1 and the lower end of the neck 3 faces toward and is `spaaced above the 4base 1. Specically, the'receptacle 2 is supported above the `base 1 at a declining angle toward the neck 3 upon legs 4 which yare iianged at their lower ends and connected to the base 1 by means of screws 5 which extend through the anges and into the base 1. The neck 3 is adjacent to and so spaced above the base 1, as to provide adequate room for the items upon which the liquid contained in the container 2 is to be dispensed, when placed Ibetween the neck 3 and the base 1. The elevated end of the container 2 is provided with an inlet neck 6 which is closed by a screw cap 7. The cap 7 has an air vent 8 extending therethrough which permits air to enter the container 2 as the liquid contained therein is dispensed.

Closing the lower end of the neck 3 is a cap 9 having an eccentric aperture 14) extending therethrough. The

RCC

cap 9 is fabricated of sheet material and has an upturned flange 9 extending about its edge. The `aperture 10 is positioned intermediate the center and the edge of the c-ap 9 and a portion of the flange 9 of the cap 9 adjacent the aperture 10 is provided with a circumferentially extending closed slot 15. A sleeve 11 is threads-bly engaged upon the neck 3 and the cap '9 slips upon and frictionally engages arc und the lower end of the sleeve i1.

A valve plate 12 having an aperture 13 therethrough is positioned within the cap 9 and is connected to lthe cap 9 for limited rotary movement. Hand actuable means, consisting of a lever handle 14, is connected to the valve plate 12 and projects exteriorly of the cap 9 for rotating the plate l2 to bring the plate aperture 13 into registry with the cap aperture 16. The aperture 13 is offset from the center of the plate l2 and the lever handle 14 extends outwardly from the edge of the plate i2 adjacent the aperture i3. The valve plate 12 rests upon the lupper f-ace oi the cap 9 and the lever handle ld extends through the slot l5 and has its exterior' portion twisted to a -su'bstantially vertical position to present a wide surface for engagement by the nger of an operator ol' the apparatus. The base of the lever arm i4 is provided with laterally extending shoulders 16 which serve las stops to engage the ends of the slot 15 so as to limit the movement of the lever arm 14. A washer 19 of thick ibrous material, is positioned within the sleeve il and seats against the lower end of the neck 3. interposed between the washer 19 and the valve plate 12 is a dimpled or concave-convex spring steel washer 17. The washer 17 is provided with a plurality of apertures iti to permit the liquid L to pass through the washer i7.

Spring means are provided upon 'the cap 9 and operatively connected to the valve plate 12 'for biasing the plate 12 to move the plate aperture 13 out of registry with the cap aperture iti. Specifically, as shown in Figure 6, the means consists of a bent ribbon spring Eil having one end sp-otwelded or otherwise rigidly connected to the flange 9 of the lcap 9 adjacent one end of the slot 15 and the other end rigidly connected to the adjacent `shoulder 16 of the lever arm id, the tension of the spring 20 forcing the lever arm i4 to the remote end of the slot i5.

A guide 21 is mounted upon the upper face of the -base 1 and connected to the base l for limited longitudinal movement upon said base. The guide 2l consists of a horizontally disposed plate having an upturned ilange positioned inwardly of and adjacent to the neck The connection between the guide 21 and the base 1 is effected by a pair of spaced pins 23 which project upwardly from the upper face of the base l anda bolt 24 which is Iixed in the base i between the pins with its shank end projecting upwardly `from the upper face of the base i, which are slldably received in closed 'slots 22 in the horizontal portion of the guide 21. A thumb nut 25 is threadably engaged upon the sh ank end of the bolt 24 and may be tightened lagainst the horizontal portion of the guide 21 to hold it releasably in any of its longitudinally adjusted positions upon the base 1.

In the operation of the described dispensing apparatus, the liquid to Vbe dispensed is poured int-o the receptacle 2 through the inlet e and `the inlet is then closed by the cap 7. The apparatus is particularly adapted to the dispensing of liquid paste or glue in a routine operation such as the gluing of `bank statements -or the like. The item-s to be glued are arranged in orderly relation adjacent the base 1 and are moved in order beneath the neck 3. When each item is properly positioned under the neck 3 the lever arm 14 is moved by the linger from the closed position in which it is held 'by the spring 20, to the opposite end ofthe slot 15, in which position the aperture 13 registers with the aperture l0 and the paste or glue flows out through the apertures and onto the work. When suicient of the liquid has been dispensed upon the work, the pressure of the linger is removed from the lever arm 14 and the spring 20 rotates the valve plate 12 back to the closed position in which the aperture 13 is out of registry with the aperture 10. The guide 21 is moved backward or forward upon the -base 1, within the limits of the slots 22 and is fixed by the thumb bolt 24 and nut 25 in such position that when an edge of the work is placed against the guide 21 the portion of the work to receive the paste or glue is properly positioned to receive it under the outlet 3. It is apparent from the foregoing that 'by the use of the apparatus of the present invention paste or glue may be applied to a large number of items in a relatively short Itime Without requiring the operator to remove his hands from the work except to the extent of raising a finger from time to time to ellect dispensing of the liquid `from the dispensing apparatus. The lapparatus will hold a substantial quantity of paste or glue at one time and can be readily refilled when necessary.

To clean the cap 9, valve plate 12 and other parts on the dispensing neck 3, which may become gummed from time to time by paste collecting thereon, the legs 4 may be disconnected from the base 1 and the container 2 set back on its flat end adjacent the inlet 6. The dispensing parts may then be removed from the neck 3 for cleaning without emptying the paste yfrom the container 2. When the parts have been cleaned and replaced upon the neck 3 the container may 'be reset in its dispensing position upon the base 1.

What is claimed is:

1. In a liquid dispensing device, a depending neck having an open lower end, a cap spaced below said lower end of the neck having -a peripheral flange, said peripheral llange having an outer side, means securing said peripheral flange around said neck, said peripheral flange having a circumferential slot, said cap having an eccentric opening, a rotatable disc Ibearing upon said cap Within said peripheral ange, said disc having an eccentric dispensing opening, arranged to lbe registered with the dispensing opening of the cap, said disc having a peripheral edge, a lever iixed to said disc and projecting outwardly of its peripheral edge and through said slot, and expanding spring means xed to the outer side of said peripheral flange and beating against a portion of said lever and outv wardly of said peripheral tiange and engaging said lever toward a position at one end of slot wherein said dispensing openings are 4out of registry with each other.
